Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The proposed rule amends the tables of classification base premium rates, experience rating plan parameters, and experience modification factor calculation limitations for the workers' compensation insurance program for calendar year 2027. Classification base rates were updated to align with expected losses. L&I proposes a 4.9 percent overall average premium rate change.

Reasons Supporting Proposal: Washington law provides that rates should be adjusted annually to reflect the hazards of each industry and in accordance with recognized workers' compensation insurance principles. L&I is proposing an overall average rate increase of 4.9 percent to ensure premiums cover most of the expected costs of 2027 workers' compensation claims. This increase is less than the indicated break-even rate and consistent with L&I's rate-making principle of keeping rates steady and predictable. This rate increase is required to account for wage inflation and other cost drivers. In addition, the increase enables L&I to maintain working capital in the supplemental pension fund which pays for annual cost of living adjustments for pensions. L&I is able to minimize the increase for this upcoming year due to accumulated investment earnings that benefit the workers' compensation contingency reserve.
